Technical Field

The invention relates to a four-wheel steering motor vehicle frame.

Background

The existing motor vehicles driven by two wheels and four wheels are only provided with directions on one bridge, the motor vehicles are slow to rotate, two wheels of the bridge with the directions rotate a large circle when turning, and the other two wheels of the bridge without the directions rotate a small circle, so that the occupied area is large, the occupied area is large when the vehicle body turns, especially when parking, and when parking, if the parking space is parallel to the road, the vehicle head enters when entering the parking space, and the vehicle tail is still outside, which is inconvenient.

Disclosure of Invention

In view of the above, the present invention provides a four-wheel-direction motor vehicle frame, which enables the front wheels and the rear wheels of a motor vehicle to steer, the wheel directions of the front axle and the rear axle are consistent, the lateral movement can be realized, and the required parking space area can be greatly reduced; the steering directions of the rear wheels and the front wheels are opposite, so that the radius required during turning and turning is minimum, and the road does not need to be occupied more.

In order to solve the problems in the prior art, the technical scheme of the invention is as follows: a four-wheel-steering motor vehicle frame characterized by: including girder and steering wheel, the girder around be provided with front axle and rear axle respectively perpendicularly, the both ends of front axle and rear axle are provided with the wheel respectively, the inboard of every wheel is provided with the steering arm, two relative steering arms pass through the place ahead to tie rod and rear direction tie rod to be connected, the place ahead tie rod on be provided with hydraulic direction machine, hydraulic direction machine passes through the rear direction to be connected with the steering arm on the wheel on the rear axle left side through the longitudinal tie rod, the connecting rod of steering wheel be connected with hydraulic direction machine and make hydraulic direction machine rotate and drive front direction tie rod and rear direction tie rod and make its wheel rotate.

The cross section of the hydraulic steering gear is T-shaped.

The crossbeam comprises two parallel vertical rods and two transverse rods vertically connected with the vertical rods.

Compared with the prior art, the invention has the following advantages:

the invention has simple structure and convenient use, and can conveniently park the vehicle in a small parking space;

the invention can correspondingly reduce the area of the parking space, so that a parking lot can simultaneously park a plurality of vehicles, and the occupied area of the parking space is saved.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

A four-wheel direction motor vehicle frame (see figures 1-3) comprises a girder 1 and a steering wheel 8, wherein a front axle 9 and a rear axle 10 are respectively and vertically arranged in the front and at the back of the girder, wheels 4 are respectively arranged at two ends of the front axle 9 and the rear axle 10, a steering arm 5 is arranged on the inner side of each wheel 4, the two opposite steering arms are connected with each other through a front transverse pull rod 2 and a rear transverse pull rod 3, a hydraulic steering gear 7 is arranged on the front transverse pull rod 2, the hydraulic steering gear 7 is connected with a steering arm on the left wheel of the rear axle 10 through a rear longitudinal pull rod 6, and a connecting rod of the steering wheel 8 is connected with the hydraulic steering gear 7 to enable the hydraulic steering gear to rotate to drive the front transverse pull rod 2 and the rear transverse pull rod 3 to enable the wheels 4 to rotate.

The cross section of the hydraulic direction machine 7 is T-shaped.

The crossbeam 1 comprises two parallel vertical rods and two transverse rods vertically connected with the vertical rods.

When the steering wheel turns left, a connecting rod of a steering wheel 8 drives a hydraulic steering gear 7 to rotate, and the hydraulic steering gear drives a front transverse pull rod 2 and a rear longitudinal pull rod 6 to drive a steering arm 5 to enable wheels to rotate in the same direction, so that the steering wheel is turned and convenient to park (see fig. 2);

when turning at the right side, the connecting rod of the steering wheel 8 drives the hydraulic steering gear 7 to rotate, and the hydraulic steering gear drives the front cross tie rod 2 and the rear longitudinal tie rod 6 to drive the steering arm 5 to enable the wheels to rotate in the same direction, so that the vehicle can turn and is convenient to stop (see fig. 3).

The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention.
