Problems solved by technology

The disadvantage is that the cylinder body is deformed after stamping, resulting in large dimensional errors, the contact surface between the cylinder body and the middle shell is small, the connection is not firm, and it will fall off and disintegrate due to vibration during driving, causing safety accidents. Therefore, the structure of the pressure cooker air chamber is improved. It has become the goal pursued by many auto parts manufacturers. Chinese patent announcement number CN2566013Y discloses a diaphragm spring brake air chamber. The cylinder body material is generally steel plate, and it also has stamping deformation, large dimensional error, Disadvantages such as poor contact

Embodiment Construction

[0027] like figure 1 In the prior art shown, the cylinder body 1 stamped by steel plate and the connection between the middle housing 2 and the cylinder body 1 of the disc spring brake air chamber are all formed by stamping steel plates. The disadvantage is that the cylinder body is deformed after stamping, resulting in The size error is large, the contact surface between the cylinder block and the middle shell is small, the connection is not firm, and it will fall off and disintegrate under the influence of vibration during driving, causing safety accidents.

[0028] like figure 2 As shown, the spin riveting spring brake air chamber structure of the present invention is mainly composed of cylindrical pin 1, clamp bolt 2, clamp 3, nut 4, tie rod bolt 5, cylinder body 6, Y-shaped sealing ring 7, brake spring 8 , energy storage piston 9, one-way valve 10, middle housing 11, diaphragm 12, front end cover 13, return spring 14, push plate assembly 15, dust cover 16, O-ring 17, sp...

Abstract

The invention discloses a spin-riveting-type spring brake chamber, a brake system adopting the same and a vehicle. The pin-riveting-type spring brake chamber is characterized in that a cylinder body is made by stretching and precisely cutting an aluminum magnesium alloy plate for a plurality of times, the surface quality of the cylinder body is good, the dimensional precision is high, and the contact surface at the joint between the cylinder body and a middle shell is large; and the cylinder body is assembled and riveted tightly through two cylindrical pins so that the cylinder body and the middle shell do not rotate relative to each other so as to ensure a firm connection.

Description

technical field [0001] The invention belongs to a motor vehicle brake air chamber, in particular to a spin riveting spring brake air chamber used in a large passenger car. Background technique [0002] At present, the cylinder body of the disc spring brake chamber (commonly known as pressure cooker) used in large passenger cars is made of steel stamping, such as figure 1 As shown, the connection between the cylinder body 1 and the middle housing 2 stamped by steel plate, and the cylinder body 1 of the disc spring brake air chamber are all formed by stamping steel plate. The disadvantage is that the cylinder body is deformed after stamping, resulting in large dimensional errors, the contact surface between the cylinder body and the middle shell is small, the connection is not firm, and it will fall off and disintegrate due to vibration during driving, causing safety accidents. Therefore, the structure of the pressure cooker air chamber is improved. It has become the goal pur...
