Problems solved by technology

[0002] The transmission is to output different speeds when the speed of the tractor’s engine is constant, and can control the steering. It can output larger torque at low speeds, and has better efficiency at high speeds, but the torque is low. Therefore, when the machine is started, it should start at a low speed, and switch to a high speed after running to maintain efficiency. Therefore, the transmission for tractors is an important drive train component. Among the existing transmissions for tractors , the transmission terminal plus side reduction gear, due to the terminal deceleration, the internal gear speed of the gearbox is high, so the noise of the transmission is large

Abstract

The invention discloses a speed changer used for a tractor. The speed changer used for the tractor comprises a speed changer body, a cone gear I (8), a two-tap position installing-changing device and a cone gear II (9), wherein the speed changer body is provided with a tap position gear (25), the cone gear I (8) is connected with a speed-changing tap position gear shaft of the speed changer body, the two-tap position installing-changing device is connected with an range shift device and the cone gear II (9) is connected with an input shaft of the two-tap position installing-changing device in a meshed mode. The cone gear I (8) is installed to be connected with cone gear II (9) in a meshed mode. Deceleration is achieved on the speed-changing tap position gear shaft of the speed changer body. The cone gear I (8) and the cone gear II (9) can be used as intermediate gears so as to enlarge a transmitting torsion of the speed changer and improve a movement performance of the speed changer.

Description

technical field [0001] The invention relates to a transmission, especially a transmission for a tractor. Background technique [0002] The transmission is to output different speeds when the speed of the tractor’s engine is constant, and can control the steering. It can output larger torque at low speeds, and has better efficiency at high speeds, but the torque is low. Therefore, when the machine is started, it should start at a low speed, and switch to a high speed after running to maintain efficiency. Therefore, the transmission for tractors is an important drive train component. Among the existing transmissions for tractors , The transmission terminal plus side reduction gear, due to the terminal deceleration, the internal gear speed of the gearbox is high, so the noise of the transmission is large. Contents of the invention [0003] In order to overcome the above-mentioned technical disadvantages, the object of the present invention is to provide a transmission for a ...
