However, since the hydraulic torque converter transmits energy through the kinetic energy of the liquid, it has a large volume, low efficiency, is not suitable for low-speed transmission, and is difficult to match with the prime mover
These problems limit the scope of use of hydraulic torque converters

Embodiment Construction
[0028] The present invention will be described in detail below with reference to the accompanying drawings.
[0029] like Figure 1-8 As shown, this piston type hydrostatic torque converter includes an input shaft 1 , a housing 2 , a variable valve 4 , a rear end cover 10 and an output shaft 9 . It also includes variable swash plate 3 , cylinder block 7 , pump plunger 5 , motor plunger 6 , valve plate 8 and transition plate 11 . The output shaft 9 is connected with the cylinder body through splines, and the output shaft 9 and the cylinder body 7 form a rotor.
[0030] like Figure 5 As shown, the cylinder part of the rotor is evenly distributed with plunger holes located in the inner and outer rings around the axis of the cylinder 7 . The inner ring and the outer ring are not on the same end face. The inner ring is the pump plunger hole 26, which is sleeved with the pump plunger 5. The inner ring part is one step higher than the outer ring part. The part is equipped with a...

Abstract
The invention discloses a plunger type hydrostatic torque converter. The torque converter comprises an input shaft (1), a shell (2), a variable valve (4), a rear end cover (10), an output shaft (9), a variable swash disc (3), a cylinder body (7), a pump plunger (5), a motor plunger (6), a return stroke disc (14), a flow distribution disc (8) and a transition disc (11), wherein the output shaft (9) is connected with the cylinder body through a spline so as to form a rotor, the variable swash disc (3) rotates around the center of an arc-shaped guide rail face of the shell (2), the input shaft (1), the pump plunger (5) and the rotor form a pump part, the motor plunger (6), the variable swash disc (3) and the rotor form a motor part, and a pump and a motor jointly use the rotor, so as to achieve high integration. The novel torque converter disclosed by the invention can achieve the functions of stepless speed regulation, soft start, overload protection, reduced impact and the like and can meet the requirements on low-speed transmission, online adjustment, reduced volume, increased efficiency and reduced cost.
Description
technical field [0001] The invention belongs to the field of hydraulic components, in particular to a hydrostatic torque converter, which is installed between an engine and a transmission, uses hydraulic oil as a working medium, and plays the roles of transmitting torque, changing torque, shifting speed and clutching. Background technique [0002] On some mechanical equipment, a torque converter is used to transmit rotary motion between the prime mover output shaft and the transmission input shaft to achieve functions such as stepless speed regulation, soft start, overload protection, and shock reduction. However, because the torque converter transmits energy through the kinetic energy of the liquid, it has large volume, low efficiency, is not suitable for low-speed transmission, and is difficult to match with the prime mover. These problems limit the use of torque converters. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a new type ...
