Problems solved by technology

[0003] According to customer feedback, when the C6J45T transmission is accelerating in 3 / 4 / 5 / 6 gears, the engine speed is in the range of 1400rpm-1800rpm, the cab handle ball vibrates severely and makes a "creaking" sound, which affects the driving experience

Embodiment Construction

[0015] After analysis and research and NVH tests, the applicant learned that the vibration of the handle ball in the cab originated from the transmission control structure of the C6J45T transmission ( figure 1 ) in the counterweight 10, the cylindrical pin 4 on the counterweight 10 is connected with the gear shifting flexible shaft, and the flexible shaft is connected with the cab handball, which can be understood as the vibration of the transmission control system is transmitted to the cab handle ball through the flexible shaft, After analysis, the jitter problem has the following two potential causes:

[0016] 1. In the control structure of the C6J45T transmission, two linear bearings ( figure 1 Marks 2 and 7 in ), during the press-fitting process of the linear bearing, the outer ring is easily deformed and then the steel ball of the inner ring is compressed to be in close contact with the outer circle of the horizontal shift lever 19 . From the perspective of vibration tra...

Abstract

The invention discloses a transmission control structure. The transmission control structure comprises a transmission control structure of a C6J45T transmission, a first linear bearing and a second linear bearing which are arranged at the two ends of a transverse gear shifting rod in the transmission control structure of the C6J45T transmission are replaced with a first lining and a second lining, the inner diameter of the first linear bearing and the inner diameter of the first lining are kept unchanged, the inner diameter of the second linear bearing and the inner diameter of the second lining are kept unchanged, and the mass of a balancing weight at the shaft end of the transverse gear shifting rod in the transmission control structure of the C6J45T transmission is reduced from 2 kg to 1 kg. The linings are not prone to deformation relative to the linear bearings in the press-fitting process, it can be effectively guaranteed that the inner rings of the linings are in clearance fit with the transverse gear shifting rod, and vibration transmission is blocked from a transmission path; and on the premise that the gear shifting hand feeling is not affected, the mass of the balance weight at the shaft end of the transverse gear shifting rod is reduced, the modal frequency is increased, and the rotating speed possibly generating resonance is transferred to a non-common rotating speed interval of an engine.

Description

technical field [0001] The invention belongs to the technical field of automobile transmissions, and in particular relates to a transmission manipulation structure. Background technique [0002] The speed changer is composed of two parts: a speed change transmission mechanism and a speed change control mechanism. The main function of the speed change transmission mechanism is to change the value and direction of torque and speed; the main function of the control mechanism is to control the transmission mechanism to realize the transformation of the transmission ratio of the transmission, that is, to realize shifting, so as to achieve variable speed and torque. In the 6-speed C6J45T transmission produced by the applicant, the highest gear is an overdrive gear, the transmission speed ratio range is 5.67-0.8, and the casing is made of aluminum. [0003] According to customer feedback, when the C6J45T transmission is accelerating in 3 / 4 / 5 / 6 gears, the engine speed is in the ran...
