Embodiment Construction

[0027] The present invention is described in detail below in conjunction with accompanying drawing:

[0028] as attached figure 1 As shown, the closed double-chamber double-row blade hydraulic retarder is composed of a left stator 1, a rotor 2 and a right stator 11. The rotor 2 is connected with the spline shaft 4 through the spline, the spline shaft 4 is connected with the rotating parts of the vehicle transmission system through the key, the left stator 1 is fixed on the mechanical transmission case 10 through the hexagon cylinder head bolt, and the right stator 11 is fixed through the hexagon The cylindrical head bolt is connected with the left stator 1, and the left stator 1 is supported by the deep groove ball bearing, and the deep groove ball bearing is axially positioned by the shoulder of the spline shaft 4 and the bearing end cover, and the bearing end cover is fixed by the hexagon socket head cap screw On left stator 1. The right stator 11 is supported by deep groo...

Abstract

The invention discloses a closed two-cavity and two-row blade hydraulic retarder. The closed two-cavity and two-row blade hydraulic retarder comprises a left stator, a rotor and a right stator, and consists of four working cavities, wherein the four working cavities comprise two circular working cavities with larger radius and two square working cavities with smaller radius; each of the circular working cavities consists of left and right semicircular working cavities; each of the square working cavities consists of left and right semi-square working cavities; semicircular blades are arranged in the semicircular working cavities; and square blades are arranged in the square working cavities. The closed two-cavity and two-row blade hydraulic retarder overcomes the defects of large diameter of circulating circles, low brake torque, slow dynamic response and axial force in a traditional hydraulic retarder; and the brake torque needed for constant-speed stepping down of long slopes and brake of a heavy-duty truck and a motor bus can be provided by the smaller diameter of the circulating circles. The hydraulic retarder, provided by the invention, has the advantages of small diameter of the circulating circles, high brake torque, quick dynamic response, balanced axial force and improved bearing working conditions.

Description

technical field [0001] The invention relates to a hydraulic retarder braking device, in particular to a closed-type double-chamber double-row blade hydraulic retarder suitable for downhill retarding and braking of heavy-duty trucks and buses. Background technique [0002] The braking and speed limit of the vehicle are extremely important, and it involves the driving safety of the vehicle. [0003] The braking torque of the hydraulic retarder is proportional to the square of its rotor speed and the fifth power of the diameter of the circular circle. A smaller size can obtain a larger braking torque, especially when the vehicle is running at high speed. The braking effect is obvious. , so the hydraulic retarder has been widely used in heavy-duty and high-power vehicles. [0004] The existing hydraulic retarder has two kinds of closed inclined blade hydraulic retarder and open hydraulic retarder, and the closed hydraulic retarder is divided into closed hydraulic retarder and c...
