Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, the clutch hydraulic cylinder comprises a cylinder body 1, a return spring 2, a spring seat 3, a leather cup 4, a piston 5 and a push rod 7, wherein the cylinder body 1 is a clutch working cylinder, the cylinder body 1 is provided with a large cylinder hole structure and a small cylinder hole structure with a middle step, the small cylinder hole is positioned on the inner side, the return spring 2, the spring seat 3 and the piston 5 are all installed in the small cylinder hole of the cylinder body 1, the outer end of the piston 5 is connected with the end of the push rod 7, and the return spring 2, the spring seat 3, the piston 5 and the.
Concrete implementation still includes location snap ring 6, and leather cup 4 and location snap ring 6 are all installed in the big cylinder hole of cylinder body 1, and leather cup 4 is located between the middle step between location snap ring 6 and the 1 big or small cylinder hole of cylinder body, and cylinder body 1 compresses tightly spacing assembly together through the axial of location snap ring 6 with leather cup 4.
As shown in fig. 2, the piston 5 is designed to be divided into two parts, namely an end part b close to the bottom of the cylinder hole and an end part a far away from the bottom of the cylinder hole, the end part b close to the bottom of the cylinder hole is used as the head of the piston 5 and is positioned in the small cylinder hole of the cylinder body 1, a blind hole is formed in the end surface of the end part b close to the bottom of the cylinder hole, a spring seat 3 is installed in the blind hole, two ends of a return spring 2 are respectively connected with a flange step at the bottom of the spring seat 3 and the bottom surface of the small cylinder hole of the cylinder body 1, an outer flange is arranged on the outer peripheral surface of the end part b close to the bottom of the; the end part a far away from the bottom of the cylinder hole of the cylinder body is positioned in the large cylinder hole of the cylinder body 1 and is in clearance fit with the inner hole of the positioning snap ring 6, so that the guide of the piston 5 during movement is ensured.
The end face of the end part a far away from the bottom of the cylinder hole of the cylinder body is provided with a concave spherical pit, the surface of the end part of the push rod 7 is a spherical surface, and the spherical surface of the push rod 7 is connected and matched with the concave pit of the end part a far away from the bottom of the cylinder hole of the cylinder body. And, keep away from end a and the leather cup 4 interference fit of cylinder body cylinder hole bottom, guarantee the leakproofness of master cylinder.
From this, when needing to change into not unidimensional cylinder hole and piston assembly relation, cylinder body 1 and cylinder hole do not change, only need to change preparation piston 5 and location snap ring 6 and can satisfy requirement and demand, and the outer flange of piston 5 keeps the unchangeable cooperation relation of size with the inner wall in the little cylinder hole of cylinder body 1 all the time.
