Embodiment Construction

[0033] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0034] Such as figure 1 As shown, it is a structural diagram of a double countershaft transmission matched with a parallel hydraulic retarder 4. A double countershaft transmission generally includes a clutch assembly 1, a housing assembly 2, and a rear cover assembly arranged sequentially along the power transmission direction. 3. The improvement of the present invention lies in that the rear cover assembly 3, the clutch assembly 1 and the housing assembly 2 remain in their original state.

[0035] Such as figure 2 and image 3 As shown in the figure, an output shaft 19 is installed at the center of the back cover 24, and the output shaft 19 is fixed with a retarder driven gear 25 through an internal spline, and a window is opened on the back cover 24 for parallel hydraulic retarding The installation and positioni...

Abstract

The invention discloses a double-intermediate shaft transmission assembly matched with a parallel hydrodynamic retarder. The key point lies in that a double-intermediate shaft transmission assembly matched with a parallel hydrodynamic retarder, which is mainly matched with the parallel hydrodynamic retarder. According to the double-intermediate shaft transmission assembly, windows are additionally formed in a rear cover, the internal structure of the rear cover of a gearbox is regulated, and a retarder driven gear is additionally arranged in an auxiliary box of a transmission to ensure that a parallel hydrodynamic retarder shaft and an output shaft rotate at a certain speed ratio; the parallel hydrodynamic retarder is deviated on one side of the rear end of the transmission when being arranged in a matched manner, so that influence on the power taking-off of a power take-off unit of the transmission is eliminated.

Description

technical field [0001] The invention belongs to the field of transmissions, in particular to a double countershaft transmission assembly matched with a parallel hydraulic retarder. Background technique [0002] With the improvement of users' requirements for the safety of vehicle braking and the promulgation of relevant regulations (GB7258), it has become a trend to equip the vehicle with a hydraulic retarder. At present, the hydraulic retarder is installed from the rear end of the transmission In terms of structural layout, there are series hydraulic retarders and parallel hydraulic retarders; it is more common to install series hydraulic retarders, mainly installed on transmissions that do not require power take-offs, such as passenger cars, and the transmission changes Smaller, but for vehicles such as dump trucks and special vehicles that need to be equipped with a power take-off, installing a series retarder cannot meet the requirements, and only parallel retarders can ...
