Problems solved by technology

The traditional hydraulic retarder adopts the control method of "electricity→gas→hydraulic", but it has the following disadvantages. 1. The control gas depends on the air source of the whole vehicle. If the pressure of the air source of the whole vehicle is unstable, or there are impurities in the gas, 2. The response speed is slow; 3. It is easy to cause the oil injection phenomenon of the retarder

Embodiment Construction

[0033] The present invention is described in further detail below in conjunction with accompanying drawing:

[0034] Such as Figure 1-4 As shown, the housing 1 of the integrated hydraulic retarder is connected to the rear cover of the transmission, and the internal oil pool is connected to share the working medium; the gear shaft 7 is constantly meshed with the large gear on the output shaft of the transmission sub-box to transmit the brake. torque. Inside the retarder, the gear shaft 7 is connected with the variable vane pump 9 through a flexible coupling 8 . The variable vane pump 9 is the core oil supply part of the retarder, which rotates at high speed driven by the gear shaft 7, and pumps oil from the oil pool to the working chamber of the retarder. The working chamber is the place where the stator assembly 6 and the rotor assembly 5 of the retarder work to generate torque. The stator assembly 6 is connected and fixed on the housing 1 through pins, and the rotor assemb...

Abstract

The invention discloses an integrated type hydraulic retarder. According to the integrated type hydraulic retarder, an oil sump is arranged under a working cavity; a heat exchanger is arranged on oneaxial side of a fixed rotor; the working cavity is connected with a variable type vane pump; the upper portion and the lower portion of the working cavity are provided with a working cavity oil inletand a working cavity oil outlet respectively; the upper portion and the lower portion of the heat exchanger are provided with a heat exchanger oil outlet and a heat exchanger oil inlet respectively. When the integrated type hydraulic retarder is in work, the working cavity, the variable type vane pump, the heat exchanger and the oil sump can form a main circulating oil way; a master control valveis used for controlling connection and disconnection of the main circulating oil way and controlled to open and close by pressure charging and discharging of a control oil way; a switch valve is usedfor controlling pressure charging and discharging of the control oil way; when the integrated type hydraulic retarder is in work, the switch valve and the master control valve are opened; when the integrated type hydraulic retarder stops working, the switch valve and the master control valve are closed, and the control oil way and the main circulating oil way are disconnected. The integrated typehydraulic retarder saves vehicle air source control and is high in response speed, stable in control and high in precision.

Description

technical field [0001] The invention belongs to the field of hydraulic retarders and relates to an integrated hydraulic retarder. Background technique [0002] On high-risk sections such as highways and mountainous areas, downhill brake failure has become a prominent problem that threatens the safety of large buses and heavy-duty trucks. The fact that there was a vicious traffic accident, and the bloody scenes were shocking. Enough attention to driving safety. As one of the auxiliary braking devices of the whole vehicle, the hydraulic retarder has been widely used in developed countries such as Europe due to its advantages of low fuel consumption, light weight, high braking efficiency and no heat fading. In my country, the hydraulic retarder is still in the stage of development and promotion. In the early stage, it was limited to some colleges and universities and scientific research institutes for theoretical research, but the research and development of the real thing is ...
