Mechanical parking device of dune buggy

Abstract

The invention provides a mechanical parking device of a dune buggy, which belongs to the mechanical technical field and solves the problem that the existing dune buggy is inconvenient to operate and unreliable in parking due to the fact that a running brake system and a parking brake system are arranged separately. The mechanical parking device of the dune buggy is connected with the tail part of a brake caliper and comprises a hand brake base, a rocker arm, a worm and a worm sleeve, wherein the worm sleeve is clamped and fixed inside the hand brake base; the inner end of the worm is arranged inside the hand brake base and is matched with the worm sleeve; the outer end of the worm stretches outside the hand brake base and is connected with the rocker arm; a piston top rod of the brake caliper stretches outside the caliper body and leans against the inner end face of the worm; when the rocker arm is rotated, the worm is driven to move forwards through the rocker arm; and a return mechanism which can make the brake caliper piston and the worm return to the initial positions when an external force acting on the rocker arm is vanished is arranged on the rocker arm. The mechanical parking device of the dune buggy has the advantages of being simple in structure, convenient to operate and reliable in parking.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a parking device for a vehicle, in particular to a mechanical parking device for an ATV. Background technique [0002] In life, ATVs are four-wheeled motorcycles, which are mainly used in tourist beach scenic spots. They are larger in size and heavier in weight. The parking brake, that is, the handbrake or the parking gear in the automatic transmission, locks the drive shaft or the rear wheels. Its function is to give the car a resistance when parking to prevent the car from rolling. The parking brake is an important part of the ATV braking system. The ATV parking brake system is an independent braking system. [0003] Existing beach car mechanical parking device is generally separated from the brake caliper, and then a parking brake control mechanism is set on the direction handle of the beach car. The brake caliper includes a caliper piston, a caliper body, a brake pad, and a...

AI Technical Summary

Problems solved by technology

When the existing parking device brakes, it is necessary to hold the brake tightly with one hand, press the parking brake block with the other hand, and use both hands at the same time. Such a device has disadvantages such as complex structure, inconvenient operation, and unreliable parking.

[0004] In addition, due to insufficient foresight of dangerous situations and poor driving ability when children are driving, they are prone to overturning, the car overturns or the car drags people away, causing injury accidents. Therefore, people are eagerly hoping that someone can design a A beach car parking device that is easy to operate and securely parks to ensure the safety of the beach car after parking
