Abstract
The invention is based on a vehicle transmission with a hydrodynamic retarder (1), the stator (3) of which is supported on a transmission housing (2) and the rotor of which is coupled with the vehicle input drive part of the transmission. The proposal is, that the stator (1) be pivotally anchored in the transmission housing (2) to rotate about the axis of rotation (17) of the rotor within a limited angular area. Further that said stator (1) is supported on at least one spring element (5, 6) on the transmission housing (2), whereby at least one spring element (6) acts upon a regulating piston (8) of the pressure regulation valve (7).
Claims5
A vehicle transmission with a hydrodynamic retarder (1), the stator (3) of which is supported on the transmission housing (2) and the rotor of which is coupled with the input part of the vehicle transmission, therein characterized, in that the stator (1) is pivotally anchored in the transmission housing (2) to rotate about an axis of rotation (17) of the rotor through a limited angle of movement and supports itself at least on one spring element (5, 6) on the transmission housing (2), wherein at least one spring element (6) acts on a control piston (8) of a pressure regulating valve (7).
A vehicle transmission in accord with one of the foregoing claims, therein characterized, in that the speed of rotation of the rotor is kept linear to the braking moment.
A vehicle transmission in accord with one of the foregoing claims, therein characterized, in that the control valve (7) can be equalized.
A vehicle transmission in accord with one of the foregoing claims, therein characterized, in that the control valve (7) can serve simultaneously for a quick filling of the retarder (1)
