Abstract

The utility model provides a vehicle frame cross beam serving as a rear support of a cab. A support cross beam of the cab is stamped by using a steel plate so as to have an upward protruded gantry form, and a middle part is an n-shaped section; the left and right ends of the cross beam are connected with upper aerofoil planes of left and right longitudinal beams of a vehicle frame respectively; the n-shaped bottom side of the middle part is connected with the upper ends of reinforced connection plates which are made from two steel plates through rivets respectively; the lower ends of the two reinforced connection plates are connected with the inner sides of lower aerofoil planes of the left and right longitudinal beams of the vehicle frame through rivets respectively, so that a frame structure with high intensity and rigidity is formed, and the function of the vehicle frame cross beam is exerted; vibration reduction rubber gaskets which have a good vibration reduction effect on the cab are arranged between the support cross beam of the cab and the cab; and therefore, the vehicle frame cross beam serving as the rear support of the cab has the functions of the rear support of the cab and a vehicle frame middle cross beam and can be widely applied to lorries with long-head cabs.

Description

The double cross member of frame of doing the operator's compartment after poppet

Technical field

The utility model relates to the Manufacturing Technology for Automotive Parts field, particularly a kind of double cross member of frame of doing the operator's compartment after poppet.

Background technology

A support must be installed on the vehicle frame of bonneted truck rear cabin position be used for rear portion, supporting driver chamber, and near this support because the needs of body frame structure for automotive intensity need to connect an intermediate transverse girder.Owing near the same position of vehicle frame, disposed two parts, thereby caused the waste of material and the increase of quality, be unfavorable for the manufacturing cost and its usage economy of automobile.

Summary of the invention

The utility model proposes a kind of double cross member of frame of doing the operator's compartment after poppet, and it can overcome the problems referred to above.

This double cross member of frame of doing the operator's compartment after poppet that the utility model provides, the cab legs crossbeam strikes out gantry shape that raises up with steel plate, and the middle part is that several shaped sections are so that it has higher rigidity and intensity.Its left and right two ends are connected with four rivets with the left and right longeron top airfoil of vehicle frame respectively; Several fonts base, middle part is connected with the reinforced company fishplate bar upper end that two rivets and two steel plates are processed respectively; Two reinforced company fishplate bar lower ends are connected with the left and right longeron lower aerofoil of vehicle frame is inboard respectively with four rivets; Form a framed structure, played the effect of cross member of frame with higher strength and stiffness.Left and right two bevel phase of cab legs crossbeam are installed a connection bearing pin with spring washer and nut after filling up large washer respectively; After loading onto a big rubber damping pad respectively, two connection bearing pin upper ends lift operator's compartment; Let two connection bearing pin tops pass operator's compartment after cross member mounting hole; On the two connection bearing pins in the operator's compartment after cross member a little rubber damping pad is installed respectively, behind the last small washer of pad a nut is installed respectively.Operator's compartment after cross member bottom and top all are equipped with rubber damping pad, and operator's compartment is had the better damping effect.This double cross member of frame of doing the operator's compartment after poppet has played the effect of operator's compartment after poppet and central frame beam crossbeam simultaneously, can reduce production costs, and help the car opertion economy, can be widely used in the goods carrying vehicle of conventional cab.

The specific embodiment

Be elaborated below in conjunction with accompanying drawing.

Shown in Fig. 1-4, the double installation matrix of doing the cross member of frame of operator's compartment after poppet is vehicle frame left side longeron 1 and vehicle frame right vertical beam 13; The supporting object of operator's compartment after poppet is operator's compartment after cross member 10 and cab floor 12, representes with long and two-short dash line, does transparence and handles.Cab legs crossbeam 2 usefulness steel plates strike out gantry shape that raises up, and the middle part is that several shaped sections are so that it has higher rigidity and intensity.Its left and right two ends are connected with rivet 3 with vehicle frame left side longeron 1, vehicle frame right vertical beam 13 top airfoils respectively; Several fonts base, middle part is connected with reinforced company's fishplate bar 4 upper ends that rivet 3 and two steel plates are processed respectively; Two reinforced company's fishplate bars, 4 lower ends are connected with vehicle frame left side longeron 1, vehicle frame right vertical beam 13 lower aerofoils inboard respectively with rivet 3; Form a framed structure, played the effect of cross member of frame with higher strength and stiffness.Cab legs crossbeam 2 left and right two bevel phase are filled up large washer 11 backs respectively one connection bearing pin 5 are installed; Two connect bearing pin 5 upper ends loads onto big rubber damping pad 9 back lifting operator'ies compartment respectively; Let two connection bearing pins, 5 tops pass operator's compartment after cross member 10 mounting holes; Punching press has two rubber pad mounting holes on the cab floor 12, can on the two connection bearing pins 5 in operator's compartment after cross member 10 a little rubber damping pad 8 be installed respectively, and a M18 * 1.5 nuts 6 are installed in the last small washer of pad 7 backs respectively.Operator's compartment after cross member 10 bottoms and top all are equipped with rubber damping pad, and operator's compartment is had the better damping effect.This double cross member of frame of doing the operator's compartment after poppet has played the effect of operator's compartment after poppet and central frame beam crossbeam simultaneously, can reduce production costs, and help the car opertion economy, can be widely used in the goods carrying vehicle of conventional cab.

As shown in Figure 2, reinforced company's fishplate bar 4 upper ends that process with two rivets 3 and steel plate on several fonts base, cab legs crossbeam 2 middle parts are connected.

As shown in Figure 3; Large washer 11 backs are installed and are connected bearing pin 5 with φ 18 spring washers 14 and M18 * 1.5 nuts 6 on the cab legs crossbeam 2 bevel phase pads; Connect bearing pin 5 upper ends and load onto big rubber damping pad 9 back lifting operator'ies compartment respectively; Let connection bearing pin 5 tops pass operator's compartment after cross member 10 mounting holes, punching press has two rubber pad mounting holes on the cab floor 12, and little rubber damping pad 8 is installed on the connection bearing pin 5 in operator's compartment after cross member 10 respectively; Small washer 7 back installing M 18 * 1.5 nuts 6 on the pad are to guarantee the bonded assembly reliability.

As shown in Figure 4, cab legs crossbeam 2 right-hand members are connected with four rivets 3 with vehicle frame right vertical beam 13 top airfoils, and reinforced company's fishplate bar 4 lower ends are connected with four rivets 3 and vehicle frame right vertical beam 13 lower aerofoils are inboard.
