Abstract

The utility model provides a transfer case of a farm vehicle. The transfer case of the farm vehicle is mainly composed of a case body, a gear, a transmission shaft, an overrunning clutch, bearings and the like. The transfer case of the farm vehicle is characterized in that the overrunning clutch does not have inner rings and is installed on the transmission shaft directly in movable fit mode, the gear is fixedly installed on an outer ring of the overrunning clutch, and the bearings are installed on the end face of the overrunning clutch in parallel. The transfer case of the farm vehicle has the advantages of utilizing unidirectional transmission performance of the overrunning clutch to achieve tolerance of linear speed error caused by dimensional error of a front tyre and a rear tyre, avoiding tyres from skidding during normal running of four-wheel driving farm vehicles or tractors, and reducing tyre wear and power loss. The transfer case of the farm vehicle is mainly applied to the four-wheel driving farm vehicles or tractors.

Description

A kind of agricultural vehicle transfer case
Technical field
The utility model relates to the agricultural vehicle of four-wheel drive or the transfer case of tractor.
Background technique
The operation of agricultural vehicle or tractor and running environment very severe; Often need four-wheel drive just can finish the work, and current agricultural vehicle or tractor four-wheel drive are to rely on gear transfer box to distribute the front and back wheels velocity ratio to realize; Because objectively there is bigger size error in the front and back tire; Its linear velocity can not be in full accord, when four-wheel drive is gone in the hard pavement, can cause front-wheel or trailing wheel to work in coordination with the mode of skidding and go; Cause tire very easily to wear and tear on the one hand, increase the excess power loss on the other hand.And present agricultural vehicle or tractor, owing to its cost reason, can not adopt advanced, be used for the differential art on the four-wheel drive car, have to be provided with manual separation mechanism, cancellation four-wheel drive when driving conditions is good.
Summary of the invention
The utility model provides a kind of agricultural vehicle transfer case, to solve the linear velocity error that the front and back tire causes because of there being bigger size error.The technological scheme of being taked is: in existing transfer case; One cover free wheel device is installed, and this free wheel device does not have inner ring, directly is installed on the transmission shaft with mode movingly; Fixedly mount driving gear on the outer ring of free wheel device; The outer ring of free wheel device and its gear can make the not necessarily rotation synchronously of gear and transmission shaft around the unidirectional relatively rotation of transmission shaft at free wheel device place, utilize the characteristic of this unidirectional relatively rotation to realize holding the front and back tire because of linear velocity error that size error produced; Avoid four-wheel drive agricultural vehicle or tractor tyre slip phenomenon in the cruising process, reduce tire wear and power power consumption.And in order to eliminate the influence of gear-driven radial force to free wheel device, the end face of free wheel device has been installed a bearing at least side by side, and this bearing and free wheel device coexist in the gear, on the transmission shaft that also coexists.
Description of drawings
Fig. 1 is the utility model sectional view.
Embodiment
As shown in Figure 1; Mainly form by casing (1), gear (2), transmission shaft (4), free wheel device (5), bearing (3) etc.; The no inner ring of free wheel device (5), directly to be installed in movingly on the transmission shaft (4), gear (2) is fixedly mounted on the outer ring of free wheel device (5); Near an end of free wheel device (5) bearing (3) has been installed; Gear (2), free wheel device (5), bearing (3) etc. are installed in the casing (1), and an end of transmission shaft (4) is in casing (1), and the other end stretches out outside the casing (1).

Claims (2)

1. an agricultural vehicle transfer case mainly is made up of casing, gear, transmission shaft, free wheel device, bearing etc., and it is characterized in that: free wheel device does not have inner ring, directly to be installed in movingly on the transmission shaft, is installed with gear on the outer ring of free wheel device.
2. a kind of agricultural vehicle transfer case according to claim 1 is characterized in that: the end face of free wheel device has been installed a bearing at least side by side, and this bearing and free wheel device coexist in the gear, on the transmission shaft that also coexists.
