[0006] In the above-mentioned existing patent, a set of link mechanism is installed between the clamp arms on both sides to coordinate the simultaneous rotation of the clamp arms on both sides. However, when the device is under normal air braking, the link mechanism also moves accordingly. And because there are many rotating pairs, it is easy to rust, which reduces the mechanical transmission efficiency and affects the braking and relief of normal air brakes. In addition, the connecting rod mechanism takes up a lot of space and has poor applicability

Abstract
The invention provides a handbrake caliper device, which is mounted on a vehicle framework and comprises a unit brake cylinder, as well as a handbrake caliper arm and a stop caliper arm mounted on the both sides of the unit brake cylinder. A connecting frame which can be mounted on the vehicle framework is connected between the handbrake caliper arm and the stop caliper arm. A hanging shaft is mounted on the connecting frame. The connecting frame is provided with a reset unit capable of increasing the horizontal degree of freedom of the connecting frame. The handbrake caliper device can solve the problem of eccentric wear caused by the heavy unit brake cylinder, the both sides of a brake disk are stressed during handbrake, and the unit brake cylinder is avoided being affected by torque.
Description
technical field [0001] The invention belongs to the field of rail vehicles, in particular to a hand brake caliper device for a rail vehicle. Background technique [0002] In order to prevent the car from slipping after parking, railway passenger cars are generally equipped with hand brakes, including hand brakes, chains, connecting rods, hand brake caliper devices, brake pads, brake discs, etc. The hand brake caliper device converts human power into brake pad pressure through the hand brake, chain, connecting rod, etc., and presses the brake disc to keep the vehicle at a standstill. [0003] like figure 1 As shown, it is a hand brake caliper device configured on an existing railway passenger car, including a unit brake cylinder 1, a hand brake caliper arm 2, a caliper arm 21, a connecting frame 4, a left rotating shaft 5, a right rotating shaft 6, a suspension Shaft 7, right brake disc holder 8, left brake disc holder 9, boom 10, hanging bolt 11 and stop bolt 12. Wherein,...
