Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of sightseeing car, more particularly to a kind of braking device for sightseeing car. BACKGROUND

[0002] The braking device of sightseeing car is the important component part for ensuring its safety in the process of driving.Sightseeing car is usually used for short-distance travel, traffic in scenic area, etc., and the design of its braking system needs to consider the weight of vehicle, driving environment, operation simplicity and safety.Common sightseeing car braking device mainly includes the following several types: hydraulic braking system is the braking mode by liquid transmission braking force, uses hydraulic oil to push brake pad or brake disc inside brake to realize vehicle deceleration or parking.Hydraulic system is higher in stability when braking, can adapt to more complex working environment, and is usually used in medium-large sightseeing car.Pneumatic braking system is the system that realizes braking by compressed air to push brake, and its advantage is that braking force is larger, and it is suitable for relatively heavy sightseeing car or large vehicle such as bus, etc.Pneumatic braking system is usually used with ABS anti-lock system to improve braking effect and safety.Electromagnetic braking system mainly brakes by electromagnetic force, and it is common in some small or electric sightseeing car.The advantage of electromagnetic braking is simple structure, no friction component, low noise, and it is suitable for using in the scene with higher noise requirement or low-speed driving.Mechanical braking is the most basic braking mode, and usually through mechanical components such as pull rope, chain, lever to transmit torque, so that brake (such as brake pad, brake drum) generates friction to decelerate.Mechanical braking system is relatively simple, and low in cost, but relatively low in efficiency, and it is suitable for some low-speed, light sightseeing car.Electric brake system is widely used in electric sightseeing car, and realizes braking function by reversing drive of electric motor.The advantage of electric brake system is that energy can be recycled, reaches certain energy regeneration function, and also helps to prolong the service life of traditional braking system.

[0003] The existing braking device generates excessive heat in the process of emergency braking, which can easily cause safety problems. UTILITY MODEL CONTENTS

[0004] Therefore, the utility model provides a kind of braking device for sightseeing car, can solve the problem that the existing braking device generates excessive heat in the process of emergency braking, and easily produces hidden danger.

[0005] The utility model is realized as follows:

[0006] This utility model provides a braking device for sightseeing vehicles, comprising a brake disc, brake pads, a brake caliper, and a hydraulic cylinder. The brake disc is fixedly connected to the axle of the sightseeing vehicle wheel and is disc-shaped, providing a friction surface. The brake caliper has a plier-like structure, and the brake pads are disposed on both sides of the brake caliper near the brake disc. The hydraulic cylinder is connected to the brake caliper. The hydraulic cylinder drives the brake caliper to rotate towards the brake disc so that the brake pads contact the brake disc to brake the sightseeing vehicle.

[0007] Based on the above technical solution, the braking device for sightseeing vehicles of this utility model can be further improved as follows:

[0008] The brake disc has ventilation grooves on its surface, which are distributed in a spiral shape to improve the heat dissipation performance of the brake disc.

[0009] Furthermore, the brake pad has an arc-shaped structure, with the same curvature as the brake disc.

[0010] Furthermore, the brake caliper consists of two X-shaped brake levers, with the middle position sleeved on the rotating shaft to define the rotation plane of the brake caliper.

[0011] Furthermore, a spring is connected between the two brake levers to reset the braking device.

[0012] Furthermore, the width of the brake pad is greater than the width of the brake disc to ensure the braking effect of the braking device.

[0013] Furthermore, the outer circumferential surface of the brake disc is provided with several ventilation holes, which are radially distributed for heat dissipation.

[0014] Furthermore, the brake pads are made of a friction material.

[0015] Furthermore, the hydraulic cylinder has a dual-piston structure, with the two pistons acting on both ends of the brake caliper respectively, to ensure that the brake pads are subjected to uniform force, thereby improving braking efficiency.

[0016] Furthermore, the brake disc is made of cast iron or ceramic matrix composite material.

[0017] Compared with the prior art, the beneficial effects of the braking device for sightseeing vehicles provided by this utility model are:

[0018] The brake disc provides the friction surface for the brake pads to contact and generate friction, thus braking the sightseeing vehicle. The brake disc is fixed to the wheel axle and is usually disc-shaped. During vehicle movement, it forms frictional contact with the brake pads, generating sufficient friction to slow the wheels down or stop them.

[0019] The brake disc surface is equipped with ventilation slots, which effectively improve heat dissipation and prevent excessive heat generation during prolonged braking, thus avoiding a decrease in braking performance. The ventilation slot design helps accelerate heat dissipation during braking, preventing overheating and brake failure.

[0020] Brake discs are typically made of cast iron or ceramic matrix composites, which have high thermal stability and wear resistance, and can operate at high temperatures for extended periods without deformation or damage.

[0021] Brake pads are friction material components that come into contact with the brake disc. Their main function is to generate friction through contact with the brake disc, thereby slowing down or stopping the vehicle. Brake pads are typically made of friction materials that have strong frictional properties and can withstand high temperatures.

[0022] Brake pads are typically wider than brake discs to ensure a sufficiently large contact area, resulting in stronger braking performance. The brake pads feature an arc-shaped structure that perfectly matches the curvature of the brake disc, ensuring uniform contact and improving braking stability and efficiency. The brake pads use high-quality friction materials that provide stable friction, preventing slippage or failure during braking.

[0023] Brake calipers are used to hold and clamp the brake pads, causing them to rub against the brake disc. The brake calipers have a plier-like structure and, through the action of a hydraulic system, press the brake pads towards the brake disc to achieve the braking effect.

[0024] The brake caliper uses an X-shaped structure, with two brake levers connected by a pivot. This design helps to define the plane of rotation of the brake caliper, ensuring that the brake pads are evenly stressed during rotation and avoiding skewed or asymmetrical contact.

[0025] Reset function: The brake caliper contains a spring to reset the braking system when the brake is released. The spring's function is to ensure that the brake pads automatically return to their original position when the brakes are not applied, avoiding unnecessary wear caused by continuous contact with the brake disc.

[0026] A hydraulic cylinder is a component used to provide driving force. Through hydraulic action, the hydraulic cylinder pushes the brake caliper to move, causing the brake pads to move closer to the brake disc, thereby generating friction and achieving the braking effect.

[0027] The hydraulic cylinder employs a dual-piston structure, with two pistons acting on both ends of the brake caliper to ensure even force distribution on the brake pads. This design improves braking efficiency and avoids situations where excessive force is applied to one side or uneven braking force may occur during braking, thereby enhancing braking stability and safety.

[0028] Precise control: Hydraulic cylinders can adjust braking force by precisely controlling oil pressure, providing a smooth and stable braking effect.

[0029] The ventilation holes on the outer circumference of the brake disc are radially distributed. These ventilation holes not only help air circulation and accelerate heat dissipation, but also help reduce the temperature of the brake disc, thereby avoiding overheating and resulting in a decrease in braking performance.

[0030] Brake discs are made of cast iron or ceramic matrix composites, which have good wear resistance and high temperature resistance, and can withstand long-term high-temperature friction without failure. Ceramic matrix composites are particularly suitable for scenarios requiring long-term braking and high performance.

[0031] The springs in the braking system not only reset the brake caliper, but also ensure that a certain gap is maintained between the brake pads and the brake disc when not braking, thus avoiding wear of the braking system due to long-term friction. Attached Figure Description
