Abstract
The utility model relates to a main reducer assembly for an automobile drive axle. The utility model is aimed at providing the main reducer assembly for the automobile drive axle with structure of an oil duct being improved, therefore oil storage and oil overflow capacities are greatly enhanced and further a lubrication effect of a bearing is enhanced. The main reducer assembly for the automobile drive axle comprises a main reducer shell, a bearing seat, an active bevel gear, a passive bevel gear and a differential assembly. The active bevel gear is mutually engaged with the passive bevel gear. The bearing seat is connected with the top of the main reducer shell via a bolt. The active bevel gear is connected with the bearing seat via a pair of tapered roller bearing. The passive bevel gear is connected with the differential assembly via another blot. The main reducer assembly is characterized in that: the built-in oil duct is arranged on the inner wall at the top of one side of the main reducer shell and is communicated with the inner chamber of the bearing seat. Preferably, one end of the built-in oil duct is communicated with the inner chamber of the bearing seat and the other end of the built-in oil duct is communicated with an oil collection chamber. The profile of the oil collection chamber is trapezoid.
Description
Technical field
The utility model relates to a kind of reducer structure, particularly the main gearbox assembly in a kind of automobile drive axle.
Background technique
The raising that quality of the life is required along with the improvement of highway in China condition and people, the singl-reduction axle technology is irreversibly towards little speed ratio, low noise, lightweight, the development of high efficiency single-stage, comfortable, safety, environmental protection, efficient and energy-conservation, become the main flow trend of commercial car development gradually.The ransaxle assembly is positioned at the end of automotive transmission, and its fundamental function is the torque that increases to be come by the transmission shaft transmission,, to the left and right driving wheel, and makes the left and right driving wheel have differential function torque distribution; Simultaneously, ransaxle also will bear vertical force, longitudinal force and the moment that acts on road surface and vehicle frame.Main gearbox assembly in existing automobile-used ransaxle mainly comprises final drive casing, bearing support, intermeshing drive bevel gear and by dynamic bevel gear, and differential assembly, bearing support is bolted the final drive casing top, drive bevel gear is connected with bearing support by a pair of tapered roller bearing, by dynamic bevel gear and differential assembly, is bolted.Because the oil channel structure on existing bearing support is external protruding oil duct, not only oil-collecting and lubrication effect are bad, also can affect the installation of retarder.In addition, the reducing gearbox of this kind structure and bearing support are because its top is oversize, and weight ratio is larger, is unfavorable for the car load loss of weight, and easily and retarder interfere, be not easy to install retarder.
The model utility content
For deficiency of the prior art, the utility model aims to provide a kind of automobile driving axle main gear box assembly that improves oil channel structure, makes the oil storage of oil duct and excessively oily ability greatly improve, thereby has improved the lubrication effect to bearing.
In order to address the above problem, this kind automobile driving axle main gear box assembly, comprise: final drive casing, bearing support, intermeshing drive bevel gear and by dynamic bevel gear, and differential assembly, bearing support is bolted the final drive casing top, drive bevel gear is connected with bearing support by a pair of tapered roller bearing, by dynamic bevel gear and differential assembly, is bolted; It is characterized in that: the inwall of a side roof part of described final drive casing is provided with built-in oil duct, and this built-in oil duct is communicated with the inner chamber of bearing support.
Preferably, an end of described built-in oil duct is communicated with the inner chamber of bearing support, and the other end is communicated with a collection chamber.The section of described collection chamber is trapezoidal.
Preferably, the top of a side of described final drive casing is connected with root via inclined-plane, and this root is vertical with axle house connecting flange.The top of described final drive casing one side and the angle α between inclined-plane are 130 °～145 °.Be provided with the triangle stiffening rib between described root and axle house connecting flange.
The beneficial effects of the utility model are: the final drive casing of main gearbox assembly, bearing support are provided with built-in oil duct and oil-collecting mechanism, the evagination oil duct of existing main deceleration shell and bearing support is designed to built-in oil duct, just can not affect the installation of retarder stator, meet and install and use requirement, and the oil storage of oil duct and excessively the ability of oil greatly improve, thereby improved lubrication effect to bearing.And considered to install the structural design of retarder interface requirement, by the reducing gearbox in main gearbox assembly and bearing support, carried out profile optimization, realized that retarder is arranged on the bridge input shaft end, reduced the impact of retarder on former car transmission system.And realized light-weight design, the improvement in cross section simultaneously reduces volume read-out.The advantages such as this singl-reduction axle is lightweight, reliability is high, maintenance cost is low, noise is low.
