Torsion buffering driver for passenger car

Abstract

The invention discloses a torsion buffering driver for a passenger car. The torsion buffering driver comprises an input shaft, the left side of the input shaft is symmetrically provided with input shaft left bosses, the right side of the input shaft is symmetrically provided with input shaft right bosses, and a first roller bearing is arranged on the left side of the input shaft left bosses; and asecond roller bearing and a third roller bearing are sequentially arranged between the input shaft left bosses and the input shaft right bosses, and a fourth roller bearing is arranged on the right side of the input shaft right bosses; and a clamping spring groove is formed in the outer side of the fourth roller bearing, a clamping spring body for preventing the fourth roller bearing from exitingis arranged in the clamping spring groove, and a ball bearing is arranged on the right side of the clamping spring groove. According to the torsion buffering driver, the problem that when vehicle starting and gear shifting are performed, the pause can be effectively solved; meanwhile, due to the fact that a lot of semi-clutch working states are reduced, the abrasion of a clutch is greatly reducedso that the consumed slipping work on the clutch can be greatly reduced, the working temperature of the clutch can be effectively reduced, and the fuel consumption during vehicle crawling and the gear shifting when in driving can be reduced.

Description

technical field [0001] The invention relates to an auxiliary device for a dry-type dual-clutch module transmission, in particular to a torsion buffer transmission for passenger cars. Background technique [0002] Regarding the status quo of the dry dual clutch in the prior art, the current dry dual clutch has its own advantages: the dry dual clutch module has a compact structure, high transmission efficiency, low fuel consumption, low production cost, and the lubricating oil used for daily operation and maintenance is only other transmissions One-third to one-fourth, so the cost is low. [0003] The advantages of the current dry dual clutch transmission: 1. Fuel saving; 2. Fast shifting; 3. Comfort; 4. There is almost no torque interruption when shifting gears. [0004] While the existing dry-type dual-clutch transmission structure has the above-mentioned advantages, the defects on the other hand caused by the structure that produces these advantages are also very prominent...

AI Technical Summary

Problems solved by technology

②Clutch wear

③ Due to the instantaneous consumption of a large amount of friction work, the clutch heats up

But the torque utilization rate is low when shifting gears; ① creeping car, under the condition of not refueling, the engine is about 900 revolutions per minute, that is, 15 revolutions per second, and the speed ratio is 13-15, so the wheels rotate about one circle per second, and the corresponding vehicle speed is about 2 meters per second, but the actual crawling speed is lower than 1 meter per second

So at this time, more than 50% of the torque output by the engine is wasted on the slipping of the clutch, and a large amount of sliding work is converted into heat, forming harmful high temperature and wear

②During a normal upshift, the engine components and the flywheel rotate at high speed, but after the upshift, their speed should decrease and the clutch can only be fully engaged after synchronization, otherwise the car will jump, but the high-speed rotating flywheel and other engine components cannot Reduced to the required synchronous speed in a very short time

Currently used measures: a. limit the output power of the engine, for example, the public needs the engine to recover before shifting gears; b. use the friction force of the clutch semi-linkage to slow down, resulting in four results: ① the advantage is no power interruption; ②Disadvantage is clutch wear; ③The high-speed rotation kinetic energy of the engine and flywheel is wasted and the dual clutch module heats up; ④The acceleration effect becomes worse

[0010] 5. There will be setbacks after using for a period of time. The dual-clutch module will wear and tear during use. It will wear and tear every time it starts, crawls, and shifts in semi-linkage. It will wear a lot in the case of stop-and-go traffic jams in large domestic cities. , and a large amount of sliding work will be converted into heat energy, because the dry dual-clutch working environment is relatively closed, which is not conducive to the heat dissipation of the dual-clutch module

② Some models will have burnt smell

④ Some models will lose power

⑤Odd or even file lost

However, the above-mentioned faults broke out without exception, and Ford also had oil leakage. For this reason, the specially designed high-temperature resistant oil seal failed to completely solve the oil leakage.

On the contrary, if the oil leaks into the dry dual clutch module, it will cause more serious setbacks
