And a dust seal groove is arranged between the piston and the shell.
The piston and the shell are fixed outside the shell only through a nut on one side of the mandrel.
And a small sealing ring is arranged at the oil hole for sealing.
The oil duct inside the shell is in a drilling mode.
The utility model has the advantages that:
1. use the utility model discloses brake cylinder can save calliper change expense, reduces expense consumption.
2. The brake caliper has high pressure resistance, the pressure bearing can reach 34Mpa, and the brake caliper can be combined into various brake calipers to be applied to a plurality of ton-grade pure electric off-highway rigid dump trucks.
3. The embedded oil passage design saves the installation quantity of external pipelines, reduces fault point positions and improves the safety performance of system pipelines.
4. The utility model discloses brake cylinder's dabber has the guide effect of piston except having piston return function concurrently, and such design makes piston housing and piston combination seal become wearing and tearing piece, greatly reduced the change quantity of spare part, practiced thrift the cost.
The utility model discloses simple structure, small, bearing capacity are high, easy maintenance, convertibility are strong, and low in manufacturing cost expense, and use brake cylinder can improve novel pure electric non-highway rigidity tipper's braking effect, ensure the safe operation of vehicle.

Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
Example (b): as shown in fig. 1, the brake cylinder of the pure electric off-highway rigid dump truck comprises a shell 1 and a piston 6, wherein the shell 1 is a hollow round cylinder with a rectangular outline, the bottom of the shell 1 is provided with a raised step and a through hole, and one side of the shell 1 is provided with an oil hole 2 which extends into the bottom of the cylinder; the piston 6 is a circular cylinder, a mandrel 14, a spring seat 15, a check ring 10 and a snap ring 11 are arranged in the cylinder of the piston 6, the mandrel 14 penetrates through a hole in a raised step at the bottom of the shell 1 and is fixed at the outer side by a nut 13, a seal 4 is arranged between the piston 6 and the shell 1, a seal ring a3 is arranged in the seal 4, a seal groove 17 is arranged between the mandrel 14 and the shell 1, and a brake oil cylinder is fixed on a front support plate and a rear support plate of a brake caliper by bolts; a dust seal groove 7 is arranged between the piston 6 and the shell 1; the piston 6 and the shell 1 are fixed outside the shell 1 only through a nut 13 on one side of a mandrel 14; a sealing ring b18 is arranged at the oil hole 2 for sealing; the oil passage in the shell 1 is drilled.
When the utility model is used, the spring seat 15 simultaneously bears the outer spring 5 and the inner spring 8, the front end of the spring seat 15 props against the outer spring 5, and the rear end props against the inner spring 8; the outer spring 5 and the inner spring 8 have the functions of clamping the mandrel 14 and resetting the piston 6; the piston 6 is reset by an outer spring 5 and an inner spring 8, return springs are designed at the same positions of the two ends of the brake pad and the brake caliper support plate, and four groups of springs are responsible for resetting the piston; the tail end of the mandrel 14 is provided with a linear opening which can adjust the stroke of the piston 6, and the nut 13 locks the adjustment degree and position; the spring seat 15 is locked by a retainer ring 11 and a locking retainer ring 10; the inner hole of the spring seat 15 on the mandrel 14 and the inner side of the inner spring 8 are lubricated by oil stored in the brake oil cylinder body; the shell 1 of the brake oil cylinder is fixed on a caliper bracket through a fixing bolt 9, a dust seal groove 7 at the extending end of the piston and a dust seal groove 7 of a piston 6 mounting hole on a supporting plate are mounted with a closed rubber dust seal together, so that mounting gaps between the piston 6 and the shell 1 are kept clean all the time, and the service lives of the piston 6, a sealing ring a3 and a seal 4 are prolonged; the seal ring b18 seals the inlet of the oil passage 2 inside the housing 1, and is responsible for sealing the joint surface of the housing 1 and the caliper.
