What Is Frameless Construction In Automobile
Aspects of Frameless Car Design 1939-01-01 MR. APPEL defines a frameless car as one in which the body is used as a structural member and in which the axles, engine, and steering gear are attached to the body, instead of having that unit used merely as a shell for passengers.

  1. The chief differences between frameless and conventional cars are summarized by stating that frameless cars: 1.
  2. Weigh about 2% less; 2.
  3. Cost less by somewhat more than 2% – where sufficient quantities are involved; 3.
  4. Are definitely more rigid; 4.
  5. Are necessary to obtain the lowest floor height; 5.
  6. Cost no more to service; 6.

are just as quiet on the road; and 7. do not involve higher insurance rates than conventional cars. Design effects brought by the frameless construction are listed as including: 1. elimination of the outside coach builder, even in Europe; 2. there can be no shifting of blame between body and chassis designers for body squeaks, rattles, and so on – the body and the chassis engineer become the same person; 3. : Aspects of Frameless Car Design

What is frame construction of a car?

Integrated frame chassis or Frameless chassis –

This frame construction, nowadays used in most of the motor cars is called frameless or chassisless or mono or unit construction in which the floor assembly and a part of the frame form one integral unbias shown in images. In this type of construction heavy side members used in conventional frame construction are eliminated and the floor is strengthened by cross members and the body, all welded together some cases subframes are also used on which various chassis components are mounted.

This sub-frame is further supported by the main frame at three points. The main purpose of using sub-frame is to provide isolation. flexibility and simplified production. Normally the structure includes an underframe or floor structure having light side member, cross members, floor and other components. They are welded together as one assembly The surface is ribbed and dished for added strengths and rigidity The pressed steel body shell is attached to the chassis frame by welding or bolting.

What is a frameless cabinet?

A frameless cabinet. Frameless construction in cabinetmaking refers to the construction of cabinets using flat panels of engineered wood — usually particle board, plywood or medium-density fibreboard — rather than the traditional frame and panel construction.

What is a chassis frame made of?

Conventional frame construction –

This type of frame is used on most heavy vehicles. For different types of vehicle, the construction details are different and varying. Chassis frames are made of steel section so that they are strong enough to withstand the load and at the same time are also light in weight to reduce dead weight on the vehicle. This type of frame has two long members and 5 to 6 cross members joined together with the help of rivets or bolts as shown in Image The cross members are used to increase the strength of frame side members may be paralleled with both horizontal and vertical planes. But more commonly taper inwards(They are inswept (narrowing) at the front and are upswept at the rear. the frame is narrowed down at the front to have a better steering lock which gives smaller turning circle and provides space for the pivoting and swinging of the front wheels. The upswept at the rear in primarily to give room for the vertical movement of the rear axle as the travels over road bumps and other surface inequalities. The body brackets are provided to support the body of the vehicle. The spring brackets are provided for mounting the spring. The extension of the chassis frame ahead of the front axle is known as front overhang, while its extension beyond the rear axle is called rear overhang. What Is Frameless Construction In Automobile The engine, clutch, gearbox, and steering are all bottled together to form a rigid assembly which is mounted usually on the front end of the frame. It is necessary that chassis must maintain the working assemblies in their correct positions and provide a mounting for the body although it adds little for the strength of the structure.
