Abstract
The invention provides a cab space expanding device used for forming the rear portion of a cab of a motor tractor. The cab space expanding device has an extending state and a retracting state. When the cab space expanding device is in the extending state, the cab space expanding device can extend relative to the rear portion of the cab, and a rotation gap between the cab and a carriage of the motor tractor is utilized. When the cab space expanding device is in the retracting state, the cab space expanding device restores, and the rotation gap between the cab and the carriage of the motor tractor is reserved. The invention further provides the motor tractor with the rear portion of the cab provided with the cab space expanding device. The space of the cab is temporarily expanded under the condition that the size of the motor tractor is not changed, the rotation gap between the cab and the carriage is fully utilized, and the better rest environment can be provided for a driver when the motor tractor stops operating.

Slide rail 241 and described glidepath 242 are used to provide slide-and-guide for described spatial spread device body 1.
Described second support slide mechanism 3 includes: tooth bar 31 and pulley 32.Tooth bar 31 is fixedly installed on described spatial spread
On device body 1, including left tooth bar 311 and right tooth bar 312, it is sleeved in the described accommodating cavity of described tooth bar chute 21,
And be equipped with described gear assembly 23, described tooth bar 31 is driven in the appearance of described tooth bar chute 21 by described gear assembly 23
It is empty in chamber and slide.Pulley 32 is fixedly installed on described spatial spread device body 1, including top sheave 321 and lower sheave
322, between described slide rail 24 and described spatial spread device body 1, described top sheave 321 moves along described upper slide rail 241
Dynamic, described lower sheave 322 is mobile along described glidepath 242.Wherein, when described tooth bar 31 is under the drive of described gear assembly 23
Along described tooth bar chute 21 slide when, described spatial spread device body 1 can accordingly slide, and described pulley 32 also can be along corresponding
Slide rail 24 is mobile.
Described tooth bar 31 is arranged in the accommodating cavity of described tooth bar chute 21, and gear assembly 23 is arranged on described tooth bar and slides
On groove 21, and this gear assembly 23 part extend in accommodating cavity, can be mutual between gear assembly 23 and described tooth bar 31
Cooperation, when gear assembly 23 rotates in the presence of motor 22, tooth bar 31 can slide accordingly.Because tooth bar 31 is fixing
It is arranged on described spatial spread device body 1, therefore spatial spread device body 1 is as well as slip.And in the present embodiment
The device that spatial spread device body 1 slidably reciprocates that can allow be not limited to only this of gear assembly 23 and tooth bar 31
Cooperation is it is also possible to select cylinder to promote or others can allow any dress that described spatial spread device body 1 slidably reciprocates
Put.
When the drive lower slider in tooth bar 31 and gear assembly 23 for the described spatial spread device body 1, due to described sky
Between expanding unit body 1 have certain weight, slide when need support and guide.The present embodiment is in slide rail 24 and described space
It is provided with pulley 32 between expanding unit body 1, be to be more convenient to slide.In the present embodiment above driver's cabin 41 rear portion
Separately design upper slide rail 321 and glidepath 242 with lower section, not only support described spatial spread device body 1, sliding simultaneously
Good guide effect, the gravity in combination gear rackwork, more conducively spatial spread device 5 sliding process is served in journey
Balance.
The distance of stretch out and draw back of described cab space expanding unit 5 is less than returning between described driver's cabin 41 and described compartment 42
Turn gap.Gyration aperture between described driver's cabin 41 and described compartment 42 is 60cm-80cm.This gap size is given enough and is driven
Room 41 reserves the space of very big confession driver rest, has both allowed driver have good rest environment, make full use of is not sharp again
Space.When tractor 4 needs to start, when driver does not need rest, spatial spread device body 1 scaling can be gone back to
Reach contraction state, do not interfere with the actions such as tractor 4 turning.
Fig. 1 shows the tractor 4 with cab space expanding unit 5.Present invention also offers a kind of tractor 4,
This tractor 4 includes driver's cabin 41 and compartment 42, thering is gyration aperture between described driver's cabin 41 and described compartment 42.In order to more
Gyration aperture between good utilization driver's cabin 41 and vehicle, also for enabling tractor 4 rest that driver has had when stopping transport
Environment, the tractor 4 providing in the present embodiment is provided with cab space expanding unit 5 at the rear portion of driver's cabin 41.This driving
Room spatial spread device 5 has extended configuration and contraction state, and described cab space expanding unit 5 is in described extended configuration
When (as Fig. 3), described cab space expanding unit 5 rear portion of relatively described driver's cabin 41 can stretch and utilize described tractor
Gyration aperture between 4 driver's cabin 41 and compartment 42.When described cab space expanding unit 5 is in described contraction state
(as Fig. 2), described cab space expanding unit 5 restore to the original state and retain described tractor 4 driver's cabin 41 and compartment 42 it
Between gyration aperture.When the stopping operation of described tractor 4, driver need rest, by described spatial spread device body 1
Stretch out the described extended configuration of arrival, to increase the space of driver's cabin 41.When tractor 4 needs operation, by described spatial spread
Device body 1 is retracted into driver's cabin 41 and reaches described contraction state, driver's normal driving.Described spatial spread device body 1 is sliding
Dynamic distance is less than the gap size between described driver's cabin 41 rear portion and described compartment 42.When described spatial spread device body
1 when being in contraction state, and the normal driving not interfering with driver is turned.Cab space expanding unit 5 in the present embodiment
Identical with cab space expanding unit 5 structure in previous embodiment, it is directed to cab space expanding unit 5 in the present embodiment
Structure division repeat no more.
In the present embodiment tractor 4 described driver's cabin 41 rear design spatial spread device 5, take full advantage of
Gyration aperture between the described driver's cabin 41 of tractor 4 and compartment 42.After driver's cabin 41 spatial spread, can internally space
Arrange the life office articles for use such as bigger bed, refrigerator, desk.When tractor does not run, cab space expanding unit 5 is in
During extended configuration, human pilot has preferable resting space and office living space；When driver's cabin runs, cab space expands
When extending apparatus 6 are in contraction state, these life office articles for use can fold the space going back to be not take up driver's cabin.Both met and drove
Sail the demand of personnel's office and rest, evade the narrow problem of the cab space that maximum full car length brings simultaneously, solve
The contradictory problems of user's request and regulation in prior art.
So far, although those skilled in the art will appreciate that detailed herein illustrate and describe the multiple of the present invention and show
Example property embodiment, but, without departing from the spirit and scope of the present invention, still can be direct according to present disclosure
