Problems solved by technology

[0005] 2. Because the screw rod 2 and the guide sleeve 3 are screwed together, the overall suspension rod 5 is multi-stage, and the overall rigidity is low
[0006] This shows that the above-mentioned existing wheel steering drive device obviously still has inconvenience and defects in structure and use, and needs to be further improved urgently.
In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but for a long time no suitable design has been developed, and the general product has no suitable structure to solve the above-mentioned problems. This is obviously the relevant industry. Urgent problem

Abstract

The invention relates to a wheel steering drive device, comprising a drive unit, a lifting rod, a hanging support arm, and a brake unit. The lifting rod is driven by the drive unit to move along a first axis, one end of the hanging support arm is connected to a wheel, the other end of the hanging support arm corresponds to the lifting rod, and the brake unit is provided with a roller wheel group arranged on one of the lifting rod and the hanging support arm, and a pair of inclines planes arranged on the other one of the lifting rod and the hanging support arm. The drive unit drives the brake unit to move along the first axis, the roller wheel group is mutually matched with the inclined planes to enable the hanging support arm to move, and thus, the purpose of controlling wheel steering is achieved.

Description

technical field [0001] The invention relates to an automobile transmission system, in particular to a wheel steering drive device. Background technique [0002] Such as figure 1 and figure 2 As shown, it is an existing wheel steering drive device (US 4973070 patent case), comprising a motor 1, two screw rods 2 driven by the motor 1, two guide sleeves 3 screwed with the screw rod 2 and two A connecting rod 4 connected with the guide sleeve 3. When the motor 1 is started, the screw rod 2 is used to drive the guide sleeve 3 and the connecting rod 4 to approach or move away from the motor 1 to achieve the purpose of wheel steering. [0003] Although this wheel steering drive device can achieve the intended purpose of use, it still has the following disadvantages: [0004] One, the motor 1 together with the screw rod 2, the guide sleeve 3 and the connecting rod 4 constitute a suspension rod 5 that produces wheel steering, which increases the unsprung weight. [0005] Second...
