Combined wedge block mechanism, lever-type anti-exceeding lock catch and automobile anti-reversed sliding device

Abstract

The invention relates to a combined wedge block mechanism, a lever-type anti-exceeding lock catch and an automobile anti-reversed sliding device. Provided is the automobile anti-reversed sliding device which is provided with the combined wedge block mechanism and the lever type anti-exceeding lock catch. The automobile anti-reversed sliding device cannot be affected by the rotation speed of a driving shaft, can effectively prevent the rotation speed of a driven rotation member from exceeding the rotation speed of a driving rotation member, can ensure the situation that an overload automobile stopped on a ramp can smoothly turn a direction, back up and head downhill, and can ensure normal driving of the automobile in advancing. The combined wedge block mechanism and the lever-type anti-exceeding lock catch are simple in structure and are reliable in working; a novel mechanical driving member is provided in the mechanical engineering general technical field; and the provided automobile anti-reversed sliding device is substantially improved in working performance.

Description

technical field [0001] The invention relates to the general technical field of mechanical engineering and the technical field of automobile engineering, and belongs to a transmission mechanism component in a mechanical transmission system, in particular to a combined wedge mechanism, a lever type anti-overrunning lock, and a lock with the above mechanism. car anti-rollback device. Background technique [0002] The patent application number is: 201110107488.4 "intermittent two-way drive mechanism, anti-rollback device with the mechanism and anti-rollback car" invention patent and patent application number is: 201210327649.5 "gap coupling, steel ball clutch and vehicle anti-rollover "Slider" invention patent, which proposes a method of using the intermittent pause time of the intermittent reversing mechanism to realize the simultaneous automatic control of the clutch during the rotation of the mechanism, so that the one-way brake connected to the transmission mechanism can be ...

[0003] According to the above-mentioned patent application number: 201110107488.4 "intermittent two-way drive mechanism, anti-reversing device with the mechanism and anti-reversing car" invention patent and patent application number: 201210327649.5 "gap coupling, ball clutch and vehicle Invention patent of anti-rollback device, the design of the anti-rollback device for automobiles, during the prototype test process, especially when it was installed on a mining dump truck with a vehicle weight of 80 tons, a design flaw was exposed: when fully loaded When the mine dump truck is parked on a ramp and needs to be reversed downhill, when the drive shaft rotates from the forward direction to the reverse direction, the original design of the centrifugal lock cannot effectively prevent it when the speed is too low. The speed of the passive rotating part exceeds the speed of the active rotating part. Under the gravity of the vehicle, the relative rotation of the driven wheel and the driving wheel is caused, causing the push pin to press the coupling teeth, causing the disengaged one-way brake to be reconnected, causing the vehicle to Unable to change direction smoothly, unable to reverse downhill smoothly
